You can use the variable EPOCH to get a timestamp before and after
execution of the read application. If the difference of the two values
evaluates to the timeout, the user enters nothing. Otherwise the user
enters '*#' or directly the #-key without anything more. I don't know
how to distinguish this two cases.
